You can access most UNSW networks from off-campus can using the UNSW VPN.

If you specifically need access inside CSE networks, you can connect to the CSE OpenVPN instead.

Install an OpenVPN client

apt-get install openvpn (or equivalent for your distribution)

Download the config file and certificate from CSE

Download cacert.pem and cse.ovpn:

Save both files in C:\Program Files\OpenVPN\config
Put cacert.pem into /etc/openvpn and cse.conf into your home directory.
Save both files to your Downloads folder, as you will be importing them from within the client.

Setting up Multiple Connections

If you connect from two different computers using the same username, the first one will be disconnected when the second logs in.

To avoid this, you can add a suffix to your username when connecting to uniquely identify your connection.

For instance, you can log in as z1234567.desktop and z1234567.laptop to have both computers connected at the same time.
